LL - stands for "Legit Laughing" and is an alternative to the very standard LOL. People say LOL when they're not really laughing. This created a need for an acronym that could express real laughter by differentiating from the commonly misused lol or it's variations. People now just say LL!

Guy1: LL will eventually replace LOL as the most used internet slang thingie.
Guy2: LL!
